Gas flow in preheating cyclone with pentagonal inlet and three core volute chamber was simulated by CFD software in this paper .

借助流体力学计算软件，对新型 干法水泥生产线上普遍采用的五边形入口、三心大 涡 壳式旋风预热器，模拟 计算了其 内部的气相流动行为。

A suction chamber is in a semi-spiral shape and an extruding chamber iss spiral volute chamber .

吸入室设成半螺旋形，压出室则设成螺旋形 涡 室；

Concrete volute chamber is a kind of spatial structure of complex shape so calculation and analysis of concrete volute chamber is very difficult .
